Answer:
Atlanta Mean price:
= Sum of all prices / Number of prices
= (340.1 + 321.6 + 291.6 + 339.6 + 359.6 + 384.6 + 309.6 + 415.6 + 293.6 + 249.6 + 539.6 + 455.6 + 359.6 + 333.9) / 14
= 4,994.2 / 14
= $356.73
Salt Lake City mean price:
= (570.1 + 354.6 + 465.6 + 219.6 + 311.6 + 297.6 + 471.6 + 618.4 + 513.2 + 381.6 + 159.6 + 267.6 + 458.6) / 14
= 5,613.3 / 14
= $400.95
I believe it is 2/12, because they each have a 1/6 probability of rolling a 6.
Answer:
y=90(0.5)^x
The y-intercept is (0,90), so when x=0, y should be 90.
By replacing x=0 in all equations you get;
1)
y=90(2)^0 =90 accepted
2)
y=2(90)^0 =2 rejected
3)
y=0.5(90)^0 =0.5 rejected
4)
y=90(0.5)^0 =90 accepted
Since this is an exponential decrease,
y=90(2)^x is rejected.
Answer:
=7/9
Step-by-step explanation:
To find the slope, we use the formula
m= (y2-y1)/ (x2-x1)
= (59-73)/(58-76)
=-14/-18
Divide top and bottom by 2
=7/9
